From SOG's web site:
Our new technical assisted folding knife line, stands out by virtue of simplicity and minimalism. It doesn’t try to be the biggest or the loudest in the crowd. It is unobtrusive but always there when you need it. Constructed from a single piece of steel, SlimJim is just that, the slimmest assisted knife in the world. Start to open the blade, and let SOG Assisted Technology (S.A.T.) finish the action with a bang, using one of the surest assisted technologies out there. Tactile bumps and cutouts aid in control while all features are purposeful and functional. The patent-pending safety is used to insure the retention of the blade in the handle as well as acts as a double lock in the open position. The stealth carry clip is reversible. Available in multiple sizes and with fully blacked out version. SlimJim, don’t let its size fool you!
